The spatial variability of dissolved arsenic (As) concentrations in aquifers was studied near Ha Noi, Vietnam. The goal was to identify major geochemical, sedimentological and hydrochemical differences between high and low As regions. Also, the behaviour of As and other elements during sequential extractions was characterized with micro synchrotron XRF analysis. Based on the results a conceptua…
Arsenic is ubiquitous in nature and has toxic effects on humans, animals, and plants. This book discusses arsenic toxicity and ways of mitigating it. It includes seven chapters that discuss arsenic sources, contamination consequences, and remediation possibilities. The chapters address arsenic and risks to human health, plant health and function, and fish and aquatic biota, as well as the chemi…
This publication presents results of an interdisciplinary field study assessing the contribution of biological and inorganic processes in the mobilisation and accumulation of arsenic in groundwater of the Bengal Delta Plain, West Bengal. Investigations were focussed on the distribution of arsenic in sediments and shallow groundwater of two representative study sites. All results were combined i…
